What is the equivalent of a 6313-2RSR bearing?

The 6313-2RSR is a 65×140×33mm deep groove ball bearing with verified equivalents across multiple brands: NSK 6313DDU, NTN 6313LLU, SKF 6313-2RS1, Timken 6313-2RS. All equivalents share the same bore, outer diameter, width, and load ratings.

What are the dimensions of a 6313-2RSR bearing?

The 6313-2RSR bearing has a bore diameter of 65mm, outer diameter of 140mm, and width of 33mm. It has a dynamic load rating of 93 kN, static load rating of 56 kN, and weighs 1380g. Maximum speed with grease lubrication is 5,000 rpm.

Can I replace a FAG 6313-2RSR with a NSK equivalent?

Yes. FAG and NSK bearings with the same ISO designation are dimensionally interchangeable. The 6313-2RSR (65×140×33mm) can be replaced with the equivalent NSK part number as long as the seal type (2RS) and clearance class (CN) match. Always verify load ratings and speed limits for your specific application.
